The power cut
by Gary Green 12 Feb '09

12 Feb '09

You will be pleased to hear that all systems are working here at YNiC following the power cut yesterday. There was slight delay in getting the scanner back on this morning because I couldn't find the fuse! I would like to publicly thank Mark Hymers for the sterling work he did last night in bringing all the systems back on-line so quickly and efficiently. The power cut was a good test of all our systems here and, it seems, that we have not lost any data or emails. Of course cluster jobs will need to restarted.

Power outage
by Mark Hymers 11 Feb '09

11 Feb '09

Hi, This evening there was a major power outage affecting YNiC. The Science Park and parts of the University were affected. Most systems were taken down in a co-ordinated manner during the period which the UPSes provided power and we believe that most user-visible systems are now up and running again. It is possible, however, that some areas have been overlooked or that there may be lingering problems. Please let the DSO know if this is the case and they will bring it to the attention of the right staff to deal with it. Any cluster jobs running at the time of the outage will be cleared and will need to be re-run. Please note that we do not intend to bring the cluster up again until tomorrow morning at the earliest and there may be some delay in getting the whole cluster running again. Sorry for the inconvenience. Thanks, Mark -- Mark Hymers York Neuroimaging Centre

[Fwd: This week's seminar at YNiC]
by Gary Green 05 Feb '09

05 Feb '09

In one hours time do come ------------------------------------ Dear colleagues This week we will discuss the design of a set of MEG and fMRI experiments that could be used to form the basis of a 'gold-standard' dataset that could be used to compare and contrast current MEG analysis techniques as well allow the testing of future analysis algorithms. Andy Young has proposed that we start this exercise by collecting data that would primarily activate sensory cortices as one should be able to predict the outcome. The aim would be to collect data in as 'perfect' a manner as possible and would include the recording of eye movements, EOG and ECG signals. The specific design of the experiments will be discussed this Thursday at 4pm. We will also discuss how we will use a suite of analysis tools to examine different source localisation and reconstruction methods. Examples of how this could be achieved will be presented by members of the YNiC team but the idea is that an analysis task-force would be encouraged to tackle the data. One of the aims is to use this data to refine our data analysis and statistical methods. We hope this will lead to clear guidelines as to the 'best' way to approach MEG experimentation and source analysis. The outcomes will determine how we develop the analysis software framework and will, hopefully, result in even clearer documentation for users as well as publications. Do come and contribute. All welcome Gary -- Gary Green York Neuroimaging Centre The Biocentre York Science Park Innovation Way Heslington York YO10 5DG

Today's YNiC Session
by Sam Johnson 29 Jan '09

29 Jan '09

Hello all, Just a quick note to let you know about this afternoon's session. The intention is to very briefly go through the talks that were given at MEG -UK and mention some of the common themes in terms of the problems people are experiencing and potential ways of addressing them. In fact these issues overlap quite heavily with the discussions planned for next week. We don't really want to preempt that discussion, so this afternoon's session will probably be quite short, and to some extent a scene setter for the debate proper on Feb the 5th. That said as ever, all are welcome. Thanks, Sam

[Fwd: YNiC seminar 15th January] - today
by Gary Green 15 Jan '09

15 Jan '09

Dear Users Today, David Halliday from the Department of Electronics will give a talk. David's talk will be followed by a YNiC project presentation by Philip Quinlan and Nikos Andreadis titled "Switching tasks and anticipating switching tasks: what is the brain doing?". These events will take place at YNiC from 4-5 pm. The title of David's talk is "The Noisy Brain – An introduction to time and frequency domain signal processing techniques for neurophysiological data". http://www.elec.york.ac.uk/staff/dh20.html Abstract: A common feature of neurophysiological signals is the presence of noise, i.e. the signals have the appearance of random processes. In addition, records taken under similar conditions do not have a similar appearance. Analysis of such data therefore requires the use of some form of statistical analysis. For example sample records of EEG recorded from different scalp locations may not look alike, but a statistical analysis may demonstrate that the records share a common underlying rhythm. The field of time-series analysis provides a conceptual and mathematical framework within which random signals, including neurophysiological signals, can be analysed. Two approaches are traditionally used in the analysis of time series – these are the time and frequency domain approaches. The frequency domain approach is generally based on Fourier methods. In the case of two or more simultaneously recorded signals, an important concept is that of correlation, the objective being to assess to what extent the activity in one signal is correlated with that in a second signal. A key frequency domain parameter in this context is the coherence function, which provides a normative linear measure of association between two time series, as a function of frequency. The talk will consider time and frequency domain analyses of neurophysiological signals, including coherence functions. These will be developed within a unified framework where time and frequency domain techniques sit naturally alongside each other, and can be used as complementary forms of analysis. A number of extensions will be discussed, which look at alternative measures of correlation (phase synchronization, causal measures); deal with time dependency (Wavelets, Kalman filtering) and non linearities (higher order spectra). Everyone is welcome to attend. Best wishes Rebecca -- ************************************************************************ Dr. Rebecca E.

Please note that the deadline is *January 11th, 2009 at 11:59 PM CST USA*. Please click here <http://www.llmsi.com/index.php?cid=1425129&forward=2670&curlid=11646> to submit an abstract. Though you are not required to register for the meeting prior to submitting an abstract, the presenter of the abstract must register for the meeting. To take advantage of the lowest registration fee, register online at www.humanbrainmapping.org/sanfrancisco <http://www.llmsi.com/index.php?cid=1425129&forward=2543&curlid=3>_2009_ by March, 15, 2009. Watch for an email announcing the opening of the registration site in January. The Program Committee (PC) of the Organization for Human Brain Mapping's goal is to keep rejection of abstracts low because it wishes to be inclusive. The policy for HBM 2009 will be to reject abstracts that are unethical, incomplete, or contain no data. Statements such as "results will be presented" are not acceptable. The PC also wants the number of posters to be at a level that will provide a positive viewing experience for the attendees. When submitting abstracts for HBM 2009, please consider whether multiple abstracts are truly necessary or if the data you are presenting could be accomplished via submission of one abstract. Thank you for assisting us in increasing the quality of the OHBM Annual Meeting. We look forward to welcoming you to HBM 2009. You can count on the traditional OHBM combination of exciting scientific programs and social events. Do plan to give yourself a little extra time to experience the city of San Francisco. This city by the sea is a bustling metropolis made famous by its most popular landmark, the Golden Gate Bridge. You won't be disappointed. The city has something for everyone. There is an excellent mix of art galleries, attractions, museums, quaint neighborhoods, unique shops, and many ethnic restaurants.

From: AHPD Departmental Contacts [mailto:AHPD-DEPTS@JISCMAIL.AC.UK] On Behalf Of John Draper Sent: 17 December 2008 15:10 To: AHPD-DEPTS(a)JISCMAIL.AC.UK Subject: FW: Call for Symposia: Annual meeting of the British Association for Cognitive Neuroscience Dear colleague, Re: Annual meeting of the British Association for Cognitive Neuroscience (BACN) I would like to invite you to submit proposals for symposia for our 2009 meeting, to be held from 21st - 23rd September at the UCL Institute of Child Health, London. The general theme of this year's meeting is 'cortical plasticity' - a broad theme, but one that is critical for understanding cognition at a number of levels: from sensory learning to language and memory. It also requires convergent methodologies and consequently we encourage you to represent the variety of modern neuroscience methods to address questions such as cognitive development, higher brain function or recovery from injury. We are also open to any alternative suggestions. We are a relatively young society that is keen to support scientists at the beginning of their career. We therefore provide several bursaries for graduate students and a poster prize for exceptional undergraduate projects, the best of whom will be invited to give a platform presentation. There will be opportunity to interact with world-leading neuroscientists from nearby UCL-based neuroscience centres (e.g. the Wellcome Trust Centre for Neuroimaging and the Institute for Cognitive Neuroscience). We also promise a lively social programme - something BACN is well renowned for! Please submit your symposium proposals by the 1st February 2009 directly to me (T.Baldeweg(a)ich.ucl.ac.uk ). Please include a provisional list of speakers and titles. Symposia usually last from 1.5h to 2.5h. Free registration for participants and contributions towards travel expenses are available. I look forward to hearing from you soon. Torsten Baldeweg Chairman BACN PS: For those of you who missed our last meeting in Swansea, a summary is published by ACNR ( <http://www.acnr.co.uk/ND08/ACNRND08_conference.pdf> http://www.acnr.co.uk/ND08/ACNRND08_conference.pdf ).

Induced and evoked responses in MEG
by awe1＠psych.york.ac.uk 16 Dec '08

16 Dec '08

Dear all The first slide in the attached Powerpoint presentation was generated by Piers for a paper based on data gathered at Aston. The stimuli were written words. The figure shows the time-frequency plots for virtual electrodes inserted at 4 different sites in the brain, with power represented in the colour. There are 3 plots for each site showing evoked power (left), total power (middle) and induced power (right). These figures were generated in Fieldtrip where the time-frequency plots are computed with respect to a baseline. Piers has added a couple of slides which shows the steps in Fieldtrip that he used. The left middle occipital gyrus (MOGl) site is closest to primary visual cortex where the words first arrive. You will notice that the power there is mostly evoked and that the induced component is small. The same is true at the left mid fusiform gyrus (= the 'visual word form area'). Contrast that with the left and right inferior frontal gyri (IFGl), which are further from primary visual cortex. There is some evoked power at those sites, but most of the total power is induced. It seems to me that the lessons could be: 1. If you plot total power, do not automatically assume that it will be mostly induced. There are conditions and sites (close to primary sensory cortex?) where the total power may be mostly evoked. 2. Do not plot total power and call it "induced". It may not be. 3. It could be that the more synapses a response passes through, the more the power shifts from evoked to induced. That could be because different stimuli complete the passage from early to late sites at different rates in different participants with the result that the response gets jittered in time, disappears in the evoked averaging, and appears instead in the induced response. Induced responses may not always be qualitatively different from from evoked responses - they may simply be smeared out in time. (Note: This is not to deny the existence of induced responses which are NOT the result of stereotypical waveforms + jitter, but rather represents increased power in several oscillators within a given time period.) 4. It would be a good thing if the VE tools we develop in YNiC for generating time-frequency plots were capable of distinguishing evoked from induced responses and plotting them separately.

We are delighted to be using for the first time The Adelphi, Liverpool, a unique and historic venue that now offers spacious conference facilities in addition to its other grand rooms and restaurants. And Liverpool is a fascinating city, fast emerging as one of the UK’s most stylish, cultured and vibrant conference venues in the UK. So why not come and enjoy some wonderful science in a truly magnificent city and see for yourself what’s been going on behind the cranes and the hoardings these past few years. The scientific programme is an exciting and topical array of seven world-class plenary speakers, 20 symposia and over 50 themed poster sessions. For the first time, there are also workshops and a satellite meeting, all FREE to registered delegates. With an equally exciting range of peripheral events and social gatherings (yes, there’ll even be a Magical Mystery Tour!) this will be a wonderful celebration of neuroscience on UK soil. So please, please do pass this message on as widely as possible as we warmly welcome non-members as well. Registration fees start from as little as £100 (including refreshments and lunches each day too), so why not consider supporting your national society next year?
